Replace the faulty CMP sensor in your 2016-2021 GM 2.8L Diesel with The Walker 235-1883 Camshaft Position (CMP) Sensor from XDP. The Cam Position Sensor can be located on the front or back of the engine block or the cylinder heads. Cam and Crank Position Sensors work together with the vehicle's ECU to ensure that both ignition timing and fuel supply are correct for peak fuel economy, performance, and emissions. Typically, your vehicle's Check Engine Light will illuminate on your dash telling you there is a code in the computer that you need to read by a repair shop. If the code says it is your CMP/CKP Sensors it does not always mean that your sensor is the bad part causing the code. Walker Products CMP/CKP sensors are 100% programmed and tested. Walker Products works continuously to stay current on all OE design changes, TSBs, and improvements to the OE design to make the best part for your vehicle. Walker Product's FSK program provides the ability to fix the vehicle the first time and not make multiple trips to the store to get what you need.

There are a number of reasons why a CMP sensor may fail. After millions of Cam and Crank rotations, the internal magnets of the sensor weaken causing poor signal transmission. A poor signal can cause improper timing between the Cam and Crank Sensor causing a check engine light and/or vehicle not starting. The repetition of extreme heat and cold, known as "heat cycling", breaks down internal circuitry. High mileage and/or poor maintenance causes an increase in tolerance stacking, resulting in sensors contacting internal rotating components. Faulty wiring and damaged connectors from heat cycling and other contaminants.
